摘　　要：采用传统的变结构控制方法设计再入子弹头的BTT控制系统,存在严重的抖振现象,并且当系统存在非匹配不确定性时,用常规方法设计切换函数,滑模稳定性难以分析。针对这些情况,设计了自适应变结构控制器,利用动态补偿器给出了较少保守的滑模稳定条件。仿真结果表明,基于自适应变结构理论的BTT控制系统设计合理,能够满足BTT控制要求。Using the traditional method of variable structure control to design the BTT control system of re-entry warhead,there exists the serious chattering phenomenon.Besides,it is difficult to analyze the sliding mode stability by using the conventional switch function design method,when there are unmatched uncertainties.In view of that,the design of the adaptive variable structure controller has less conservative stability conditions for the sliding mode by using the dynamic compensator.The simulation results show that the BTT control system based on the theory of adaptive variable structure control can fulfill the BTT control system requirements.
